Answer:
The quantity after t years 40 (0.65)^{\textrm t} millions tons
Step-by-step explanation:
Given as :
The rate of decrease of carbon dioxide each other = 35%
The quantity of carbon dioxide emitted this year = 40 million tons
Let the quantity of carbon dioxide emitted after t year = A millions tons
Now, According to question
The quantity of carbon dioxide emitted after t year = The quantity of carbon dioxide emitted this year ×
Or, A millions tons = 40 millions tons ×
Or, A millions tons = 40 millions tons ×
Or, A millions tons = 40 millions tons ×

Answer:
(6,2)
Step-by-step explanation:
Variable Definitions:
x= the number of commercials
y= the number of movies
Each commercial earns Emily $50, so x commercials would earn her 50x dollars in royalties. Each movie earns Emily $150, so y movies would earn her 150y dollars in royalties. Therefore, the total royalties 50x+150y equals $600:
50x+150y=600
Since Emily's songs were played on 3 times as many commercials as movies, if we multiply 3 by the number of movies, we will get the number of commercials, meaning x equals 3y.
x=3y
Write System of Equations:
50x+150y=600
x=3y
Solve for y in each equation:
1) 50x+150y=600
150y=−50x+600
y=-1/3x+4
2) x=3y
y=1/3x
The x variable represents the number of commercials and the yy variable represents the number of movies. Since the lines intersect at the point (6,2) we can say:
Emily's songs were played on 6 commercials and 2 movies.
Answer:
at least 6
Step-by-step explanation:
3(.5x+3)>12
1.5x+9>12
1.5>9
x>6
